MEANS FOR HOLDING LOOSE MEMBERS OF MACHINES UPON ENDS OF STUDS OR SHAFTS.

SPECIFICATION forming part of Letters Patent N 0. 679,843, dated August 6, 1901.

Application filed June 6, 1901. Serial No. 63,494.. (No model.) I

To all whom. it may concern.-

Be it known that I, BENJAMIN HOLLAND, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Means for Holding Loose Members of Machines upon the Ends of Studs or Shafts, of which the following is a specification.

The nature of my invention consists in the employment of a notched and deflected cotterwasher, in combination with a cotter-pin, for holding loose members of a machine upon the end of a stud or shaft.

In the accompanying drawings, Figure 1 represents a perspective View of the notched and deflected cotter-washer. Fig. 2 represents a face viewof the same. Fig. 3 represents an edge View. Fig. 4 represents a side view of a stud provided with the notched and deflected cotter-washer and its accompanying cotter-pin. Fig. 5 represents an end view of the same. Fig. 6 represents an axial section.

In the drawings, A represents a metallic washer provided at the edge with the notch b, adapted to receive the cotter-pin O, the opposite lips 11 d thus formed being both deflected in the same direction, as shown in Figs. 1 and 3. In using this improved cotter- Washer the WasherA is placed'upon the end portion B of the stud or shaftD and the cotter-pin C driven through the hole a, made therefor, the loose member of the machine being held between the innerside c of the washer A and the shoulder c of the stud or shaft, and by means of the notch Z1, into which the end of the cotter-pin 0 passes, as shown in Fig. 5, the cotter-washer A will be prevented from movement relatively to the cotter-pin, where by the wear of the cotter-pin and the result= ing increased looseness of the included member of the machine will be avoided.

A great advantage resulting from my invention is shown in Fig. 6, which shows the head and point of the cotter-pin deflected toward the washer, whereby the space between the face 0 of the washer and the shoulder a may be lessened, so as to insure the proper closeness of fit, the deflection of the end of the cotter-pin within the notch of the washer serving to eifect this object without a disfiguring projection.

I claim as my invention- 1. A cotter-washer provided with a notch at its edge, and the deflected lips at each side of the notch, substantially as described 2. The combination of a cotter-washer provided with a notch at its edge and the deflected lips, with the cotter-pin passing through the stud or shaft and into the notch of the washer,

substantially as described.
